Best Buy has officially kicked off its Black Friday in July sale, and it's full of some great LEGO deals. From the Super Mario World: Mario \& Yoshi set to the Star Wars Acclamator-Class Assault Ship to the Marvel Avengers: Age of Ultron Quinjet, we've rounded up some of our favorite offers available in this sale right now below. But act fast, as they won't last for long.

You've got until this Sunday, July 26, to grab your favorite sets as part of this sale, so the clock is ticking. There's every chance some of these sets could sell out, too. So if you come across one you really want to have in your collection, now is the time to buy it.

Some of the sets we've highlighted above are soon to be retired as well, so this is an excellent opportunity to scoop them up for less before they're gone for good. Among that group is the Star Wars Acclamator-Class Assault Ship set (which is even out of stock right now on LEGO's website) and the Mario Kart Baby Peach \& Grand Prix set.

The Super Mario World: Mario \& Yoshi set is also rumored to be part of this group, though LEGO's website doesn't have a 'Retiring Soon' tag on it as of the time of this writing. With that in mind, I think it's safe for now, but you never know when its time will come. Plus, if you grab it now, it's even cheaper than the price we saw during Prime Day, which is a huge bonus.

This is a nice little surprise drop of LEGO deals, and we may not see offers like this pop up again for a couple of months until the next big sale event starts. So, if you see sets from Best Buy's sale that have been on your wishlist, now is the time to grab them before the deals disappear this Sunday.
